I give A+ to Directbet! They are #1!
they are A+ for most of bitcointalk community members i know it, but we can't ignore current directbet case about a double spending attempt and confiscated funds worth thousands dollar. complicated case and still no solution to solve the problem.
Even without the recent case of the double spend issue, you wont ever see directbet in the A+ list. Peeps got his own reason on not putting them on the A+ list which is because they were an onchain gambling sportsbook so the time of the odds confirmed will never be as instant as the other offchain sportsbook
